Can do.
次ぎに、本発明の水中環境改善素材の実施の形態について説明する。 Next, an embodiment of the underwater environment improving material of the present invention will be described.
本発明の水中環境改善素材は、少なくとも黒鉛珪石と生分解性樹脂とを有効成分として有している。 The underwater environment improving material of the present invention has at least graphite silica and a biodegradable resin as active ingredients.
本実施形態置に用いる生分解樹脂としては、海等に設置されて生分解するものであれば殿ようなものであってもよく、例えば、ポリ（ヒドロキシブチレート／ヒドロキシバリレート）コポリマー等の微生物生産型、ポリエチレンサクシネート、ポリブチレンサクシネート、ポリカプロラクトン等の石油合成型、ポリ−Ｌ乳酸等の植物合成型、澱粉＋ポリビニルアルコール等の天然高分子型等を挙げることができる。 The biodegradable resin used in the present embodiment may be anything as long as it is installed in the sea or the like and biodegrades, such as a poly (hydroxybutyrate / hydroxyvalerate) copolymer. Examples include microorganism production types, petroleum synthesis types such as polyethylene succinate, polybutylene succinate, and polycaprolactone, plant synthesis types such as poly-L lactic acid, and natural polymer types such as starch and polyvinyl alcohol.
本実施形態置に用いる黒鉛珪石としては、天然に産出される黒鉛珪石を用いるとよい。 As the graphite silica used in the present embodiment, naturally produced graphite silica may be used.
さらに、必要に応じて天然繊維を混入させるとよい。 Furthermore, natural fibers may be mixed as necessary.
これらの有効成分の割合は、どのような割合でもよい。 The ratio of these active ingredients may be any ratio.
例えば、溶融状態の生分解樹脂中に黒鉛珪石を混練りさせて成型する場合には、黒鉛珪石を約３〜１５重量％（好ましくは約１０重量％）、生分解性樹脂を８０〜９７重量％（好ましくは約９０重量％）、その他の不可避的混入物とするとよい。黒鉛珪石が３重量％より少なくなると黒鉛珪石による環境改善効果が少なくなり、１５重量％より多くなると樹脂成形が困難となるからである。 For example, when graphite silica is kneaded into a molten biodegradable resin and molded, the graphite silica is about 3 to 15% by weight (preferably about 10% by weight), and the biodegradable resin is 80 to 97% by weight. % (Preferably about 90% by weight) and other inevitable contaminants. This is because if the amount of graphite silica is less than 3% by weight, the effect of improving the environment by the graphite silica is reduced, and if it exceeds 15% by weight, resin molding becomes difficult.
また、溶融混練り状態の生分解樹脂および黒鉛珪石中にさらに天然繊維を混入させる場合には、海況に応じて天然繊維を混入させるとよい。 When natural fibers are further mixed in the melt-kneaded biodegradable resin and graphite silica, the natural fibers may be mixed according to the sea conditions.
水中環境改善素材を環境改善位置に設置するためには、前記の溶融混練り上の生分解樹脂と黒鉛珪石さらには天然繊維を公知の方法によって樹脂成形することにより、ロープやトワインやひも状の長尺物としたり、面上のシートやフイルムとしたり、繊維とするとよい。また、トワイン等の長尺物を用いて網を製造したり、繊維を用いてフェルト状等の不織布を製造してもよい。さらに、前記有効成分全体を塗料状に形成してもよい。 In order to install the underwater environmental improvement material at the environmental improvement position, the above-mentioned melt-kneaded biodegradable resin, graphite silica, and natural fiber are resin-molded by a known method, so that the rope, twain or string-like material is formed. It may be a long object, a sheet or film on the surface, or a fiber. Moreover, you may manufacture a net | network using elongate objects, such as twain, and may manufacture nonwoven fabrics, such as a felt shape, using a fiber. Further, the entire active ingredient may be formed in a paint form.
このように形成されている本実施形態の水中環境改善素材のうち、網、シート、フイルム、不織布等の面状物は、岩礁や魚礁等を覆うようにせっちするとよい。また、長尺物や繊維によっては、面状物の素材としたり、さらには、直接岩礁や魚礁に結びつけて設置するとよい。また、塗料状の水中環境改善素材は、岩礁や魚礁の表面に直接塗布してもちいるとよい。 Of the underwater environment-improving material of the present embodiment formed as described above, a planar object such as a net, a sheet, a film, or a non-woven fabric is preferably covered so as to cover a reef or a fish reef. Depending on the length of material or fiber, the material may be a surface material, or may be directly connected to a reef or fish reef. In addition, the paint-like underwater environment improving material may be applied directly to the surface of a reef or fish reef.
次ぎに、本実施形態の作用を説明する。 Next, the operation of this embodiment will be described.
種々の形態を有する本発明の水中環境改善素材は、岩礁、魚礁、人工構造物等の水中環境を良好に維持すべき設置場所への設置態様を、長尺物、網、シート、フイルム、不織布、繊維、塗料の中から当該設置場所の状態に応じて適正な形態の水中環境改善素材を選択して設置させる。 The underwater environment improving material of the present invention having various forms is a long object, a net, a sheet, a film, a non-woven fabric, and an installation mode in an installation place where the underwater environment such as a reef, a fish reef, and an artificial structure should be maintained well. From the fiber and paint, select and install an underwater environment improvement material in an appropriate form according to the state of the installation location.
このようにして設置場所に設置された本実施形態の水中環境改善素材においては、生分解性樹脂が自然と分解する。そして、当該生分解性樹脂の表面や樹脂中にある黒鉛珪石若しくは生分解性樹脂より離脱した黒鉛珪石が、自ら保有する環境改善機能を発揮して水質を改善させ、さらに生分解性樹脂は自然と分解されることにより環境汚染を発生させることのない環境に優しいものとなる。 Thus, in the underwater environment improvement material of this embodiment installed in an installation place, biodegradable resin decomposes | disassembles naturally. And the surface of the biodegradable resin, the graphite silica in the resin, or the graphite silica separated from the biodegradable resin, exerts its own environmental improvement function to improve the water quality. By being decomposed, it becomes environmentally friendly without causing environmental pollution.
さらに説明すると、黒鉛珪石は水と直接ふれることにより、ふれた水に電子を流すことができたり、遠赤外線を発射することにより、水中生物である藻類や魚介類等の生存環境の健全化効果を十分に発揮することとなり、水質を改善させて、磯焼けや赤潮、青潮の発生を防止することができる。 To explain further, graphite quartz stones can directly flow into water by touching the water, and by emitting far-infrared rays, the aquatic living environment such as algae and seafood, which are aquatic organisms, can be healthy. Can be fully exerted, improving water quality and preventing the occurrence of firewood burning, red tide and blue tide.
なお、本発明は、前述した実施の形態に限定されるものではなく、必要に応じて種々の変更が可能である。
In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.
